In several of these specimens the elj'tral bands are more distinct than 

 in others. This species is clearly a member of the citrina group. 



Trimerotropis latioincta Saussure. 



Carr Canyon, Huachuca Mountains, August, 1905 (Skinner), 1 c? ; 

 October 8 and 20, 1905 (Biederman), 3 cJ* , 2 9 . Palmerlee, September 

 (Schaeffer), 1 cJ*. Douglas, August (F. H. Snow), 1 d"'. 



These specimens are true laticincta, although the validity of this as 

 distinct from latifasciata appears rather doubtful. 

 Trimerotropis magnifica n. sp. 



Type: c? ; Carr Canyon, Huachuca Mountains, Cochise Co., Arizona. 

 August, 1905 (Henry Skinner). [A. N. S. Phila.] 



This very large and striking new species is allied to T. tolteca and 

 fistrinaria Saussure, but differs from both in the very much greater 

 size, and from tolteca in the presence of a hyaline distal section on the 

 wings, as well as from pistrinaria in the practical absence of the usual 

 ulnar spur on the wing. 



Size very large (for the genus); form moderately robust. Head 

 with the occiput rounded and slightly elevated above the level of the 

 disk of the pronotum, interspace between the eyes as broad as the 

 greatest width of the disk of the fastigium; fastigium considerably

declivent, the slope of the same being a regular continuation of the arch 

 of the occiput, lateral carinae of the fastigium parallel caudad, regularly 

 approaching one another cephalad, median carina faintly indicated 

 caudad; lateral foveolse undefined, no ventral bounding ridge in the 

 usual position; frontal costa considerably constricted dorsad, broader 

 and subequal for a distance dorsad and ventrad of the ocellus, on the
